In the present study, influences of cold rolling and annealing time on fatigue crack propagation behavior AA5052 aluminum alloy were investigated. The sheet was cold-rolled under different reductions, i.e., 0, 15, 30, 45%. 45% as-rolled specimen then annealed at 370°C times, for 2, 4, 6 h. microstructure evolutions after treatments also examined using optical microscopy whereas characterized by...

the aim of this study was to investigate the effect of feeding of  steeped barley grain with lactic acid (la) and citric acid (ca) on dry matter intake, feeding behavior, apparent nutrients digestibility, rumen ph and milk production. eight early lactating holstein cows in the second parities were used in 4×4 latin square change- over design. treatments  consisted of basis diet containing 1) dr...

The hands and fingers are common sites of injury, accounting for an estimated 4.8 million injured persons treated in US hospital emergency departments in 2001 alone.

An emerging solution to privacy issues in smart grids is battery-based load hiding (BLH) that uses a rechargeable battery to decouple the meter readings from user activities. However, existing BLH algorithms have two significant limitations: (1) Most of them focus on flattening high-frequency variation of usage profile only, thereby still revealing a low-frequency shape; (2) Otherwise, they ass...
